It's Always Sunny in Philadelphia, Season 4

Mac:
Kaboom!

Dee:
Surprise, bitches! We're alive and it's blowing your minds right now!

Charlie:
Hahahahahaha!

Dennis:
No, it is not blowing our minds at all. I knew you guys were alive.

Charlie:
Huh?

Dennis:
Yeah, I knew you guys were alive, okay? I figured it out right before the funeral.

Mac:
How?

Dennis:
'Cause I could hear you guys rustling around in the vents. You were speaking at full volume. Okay? Did you think you were being like crafty? And I could see you staring at me through the window. You know I can see through my windows, right? I wanted to piss you off.

Dee:
Well what about me? Did you want to piss me off?

Dennis:
Uhh...you I thought might have actually been murdered.

Dee:
That's what I thought.

Charlie:
So hold on a second. So, Frank, you knew too?

Frank:
Yeah...[meekly nodding] I knew.

Charlie:
And some of this stuff you've been doing with this mannequin here, that's like uh...to teach me a lesson or...?

Frank:
[Long pause] Yeah.

Charlie:
Did I see you bang that thing?
